lMPROVEMENT IN SELF-HEATING SAD=|RONS.

Specification forming part of Letters Patents No. 1633 &2, dated May 18,1875; application filed March 15, 1875.

To all whom it may cocrn Be it known that I, ROBERT H. HASENRIT- TER, ofHermann, in the county of Gasconade and State of Missouri, have inventedcertain new and useful Improvements in SadIrons; and I do hereby declarethat the following is a full, clear, and exact description thereof,which Will enable others skilled in the art to which it pertains to makeand use the same, reference being had to the accompanying drawing, andto the letters of reference marked thereon, which form a part of thisspecification.

My invention relates toimprovements in sadirons which are heated by fireplaced within them. It consists in a removable partition placed acrossthe front end of the chamber, dividing the latter into two compartmentsone for the reception of the fire, the other for a flue or for thereception of a removable chimney-there being no communication betweensaid compartments except under said partition; in constructin g the lidin two parts, the front part being formed so as to neatly fit over and,when desired, close in the front compartment, and is hinged or journaledin the side walls of the iron. The rear part of the lid closes in therear compartment, and is hinged or journaled to the walls, so that itcan be turned up toa vertical position.

In the drawings, Figure l is a plan view with the lids removed, Fig. 2 alongitudinal vertical section, and Fig. 3 a cross-section, of myinvention.

A- are the side plates or walls, curved at their front ends, in theusual manner, to form the point. B is the rear end plate, so constructedas to leave the opening C between it and the bottom plate for thepurposes of draft. D is a slide-valve for closing or opening thedraft-passage O. E is the bottom plate, made with the extension E onwhich is formed the external chamber E which prevents ashes or dust fromfalling out of the fire-box or com partment onto the clothin g. F are aseries of parallel vertical ribs attached to the bottom plate E. Theyhave a depth equal to about one-sixth the depth of the iron. They extendfrom the rear end toward the front. The center rib extends to and isattached to the inner angle of the point. The lateral ribs do notconnect at their front ends with the walls, but there is space left, soas to permit free passage of air around them. They form reetangularrecesses or troughs, and prevent the fuel from packing too closely onthe bottom, and increase the draft by affbrding narrow passages, throughwhich the air passes; and when the bottom plate becomes covered withashes they make a connecting medium from the fire to the plate E, sothat a uniform heat is preserved in said plate. Gr is a partition,dividing chamber of the iron into the two compartments Gr G It isinserted in grooves formed in the walls A at the point where the latterbegin to ourve inward to form the point of the iron. It rests on theribs F, and cuts off all communication between the compartments, excepta narrow passage on its under side. llt may be solid or perforated, asindicated in dotted lines, Fig. 3.

When it is desired to increase the quantity of fire the solid partitionis taken out and the perforated one inserted. The draft, passing throughthe fuel to the perforations, causes a more rapid combustion, and, as aresult, greater fire and heat. When the solid part-ition is used thedraft is along the bottom within the rectangular passages formed by theribs, and the combustion is confined to the under portion of the fuellying along and near the bottom plate.

The lid is formed in two sections, H H'. The rear section H closes thecompartment Gr It is hinged by screws or other means in the walls A at aa, so that it can be turned up to a vertical position, and thus open thefire-chamber for any desired purpose. When turned down, it is held inplace by a shoulder on the front section H', hereinafter described. Anysuitable means for holding its front end down may be used when the frontsection is turned down, so as to take the shoulder from its positionabove the end. The front section H' of the lid neatly fits over thetriangular compartment (3 It is secured by suitable means to the walls Aimmediately above the partition G, and so that it can be raised to avertical position. It is provided with the flange or shoulder b, and,when raised to a vertical position, this shoulder projects over andagainst the front end of the section H, and holds the latter firmly inplace, and prevents the front section from turning back past a Verticalposition. Its edges extend out flush with the sides A, the latter beingsufficiently cut down to admit of the tops of both sections being flushwith each other. It is held in an upright position by the spring-catchc, Secured to the side A. I is the chinney, constructed to fit neatly inthe compartment G Its lower Front side is slightiy cut away to admit ofdraft through the perforations in the partition Gr. It may be removed orinserted at pleasure.

It will be seen that the draft will be along bottom of the chamber inthe rectangular passage-ways formed by the ribs, and that the heat willbe more evenly distributed over the bottom plate; that the point of theiron will be kept hot by the heat passing directly over the plate fromcompartment G', that when, by reason of Consumption of fuel, the ashesaccumuiate on the bottom, the heat of the bottom plate will be preservedby the conducting property of the ribs,which extend up into the fire;that, by removing or inserting the chimney, the draft can be lessened orincreased; that,when desired to have a greater amount of fire, theperforated partition canbe inserted, and the draft made to rise throughthe fuel, and cause more rapid Consumption of the latter; that therequisite degree of heat is preserved in the smoothing-plate with slightConsumption of fuel; and that the Compartments can be entirely closed,so as to extinguish the fire by cutting ofi' draft and supply of airfrom any point.

Having described my invention, what I claim and desire to secure byLetters Patent, s-

1. The combination, with a box-iron, of the removable partition G, solidor perforated removable chimney I, and spring c, for the purposesspecified.

2. The com bination, with the body of a boxiron, of the lid constructedin the two sections H (which is provided with the shoulder b) and H',(which is journaled or hinged in the side plates A,) substantially asand for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.
